Why Waters 1525M Water Pump makes click or loud snap?
A click or loud snap in your Waters Water Pump can be caused by a binding plunger seal. If the click does not stop and cannot be isolated to one pump head, replace the plunger seals, one at a time. It can also be caused by a worn indicator rod spring, in which case you should replace the spring.
Why Waters 1525M baseline noise cycling, short-term (30 to 60 sec)?
Short-term (30 to 60 sec) cycling baseline noise in your Waters Water Pump can be caused by a fluctuating flow rate. Degas the eluent and try repriming the pumps. If necessary, check the flow accuracy of the pumps. Inadequate eluent blending can also cause this issue; install a mixer. Power source issues can also contribute to cycling noise; disconnect other instruments on the power line, try a different wall outlet, have the line voltage checked, or use the power conditioner. Radio frequency noise can also be a factor; eliminate interference.
Why Waters 1525M baseline noise cycling, long-term (for 1 hour)?
Long-term (for 1 hour) cycling baseline noise in your Waters Water Pump can be caused by ambient temperature fluctuations; stabilize the ambient temperature. It can also be due to a faulty integrator or recorder; check the integrator or recorder for excessive baseline noise.
